The e-Stroke GEN 3 Disc System is designed to continuously monitor Disc (or a

combination of drum and disc) vehicle air brake systems both while in operation and

during stationary brake inspections. The e-Stroke GEN 3 system also includes various

diagnostic capabilities as described in this guide.

The MGM e-Stroke system utilizes piston rod travel measurements from the brake

chambers, as well as brake application pressure and vehicle speed, to determine the

overall status of the brake system. In addition the e-Stroke GEN 3 system is also

capable of monitor lining wear if installed with the appropriate lining wear sensors. The

MGM e-Stroke disc brake chambers are similar to MGM Brakes standard chambers, with

the addition of a sensor pack which mounts in between the actuator and caliper, and a

specially designed spring loaded pushrod that detects caliper lever arm movement. MGM

e-Stroke disc brake actuators use an infrared sensor and reflective target material,

located on the pushrod, to measure brake stroke. At the center of the e-Stroke system is

the Chassis Communication Module or CCM, which accepts all of the systems inputs and

outputs and utilizes proprietary MGM software to monitor the vehicles braking system.

STEP 2: Installation of Chassis Communications Module (CCM)

2.1: Choosing the CCM Mounting Location

2.1.1: The CCM must be mounted within 1 meter of the J1939 access. SAE

specifies that J1939 drop leg extensions are limited to 1 meter in length

from the J1939 backbone. The location of the available J1939

connections will determine the CCM mounting location for most retrofit

applications. The communications closet behind the driver’s seat (for

bus applications where equipped) is the recommended CCM mounting

location, as J1939 and ignition switched power are typically available. In

addition, the e-Stroke GEN 3 CCM is not environmentally sealed

requiring interior installation. Reference Step 4, 5.

2.1.2: Choose a CCM mounting location which provides accessibility for

Technicians. Access to the CCM is required for diagnostic

troubleshooting. See Figure 4.

• The CCM includes a Red Push Button on the face for initiating

warning light blink codes. Reference Step 9.3.

• The CCM “P2” connector needs to be accessible to connect the RS-

232 Diagnostic Harness. Reference Step 9.1.

2.1.3: It is recommended that at least 2” of space is left around the CCM on all

sides. Care should be taken to avoid exposure to anything that could

damage the connectors or the module itself. See Figure 4.

2.1.4: Mount the CCM in an orientation which allows the Technicians and

Operators to clearly read the text on the front of the CCM (Not upside

down or sideways from the Technicians perspective). See Figure 4.

2.2.2: Fastener Mounting

• Use the CCM as a template for locating the mounting holes.

• Drill appropriately sized holes for the mounting fasteners to be used. Two

¼” fasteners are recommended. Locking nuts are recommended for

machine screw type fasteners.

• Always use care when drilling any surface as critical components may be

behind the drilled surface.

• Install CCM using mounting tabs and selected fasteners.

STEP 3: Installation of Pressure Transducer & Harness

3.1: Choosing the Pressure Transducer Mounting Location

• The e-Stroke pressure transducer is intended to measure brake

application pressure.

• The recommended mounting location for the pressure transducer is at

the Brake Treadle Valve Secondary Delivery Output.

• Bus applications typically have a treadle valve output manifold with

multiple ports containing other pressure switches and transducers.

• Tractors & Trucks may have a spare port on the treadle valve body.

3.2: Pressure Transducer Mounting

3.2.1: The e-Stroke pressure transducer includes a ¼” NPT male fitting. Either

locate a spare ¼” NPT port in the brake treadle valve secondary delivery

output or add one using standard ¼” NPT brass fittings. See Figure 5.

3.2.2: Install the pressure transducer into the air-port using approved thread

sealer. Verify the connection to be leak free after installation.

6.2.4: Route the warning light harnesses to the CCM securing harness every 12-18” with UV resistant (Black) cable ties.

6.2.5: Connect the warning light harnesses to the CCM as follows:

• Alarms 1 & 2: Connect the Warning Light Harness to the appropriately labeled leads on the CCM power harness (P/N 8290233) which is connected to the CCM “P1” Connector.

• Alarms 3 & 4: Connect the Warning Light Harness to the appropriate labeled Warning Light Adapter Harness (P/N 8290235) lead which is connected to CCM P15 Connector. (Tractor Applications Only)

STEP 7: Sensor Harnesses (Routing & Installation)

IMPORTANT: Using proper harness installation practices is the most

important action which can be taken to ensure the long term

durability of the e-Stroke system.

Reference Service Bulletin EB 13-001 for additional harness

installation instruction.

7.1: Label both ends of each Sensor Harness for ease of Identification at CCM and Sensor.

Note: Care should be taken to ensure that connections on the wheel ends will match designations on the CCM, otherwise the displayed fault may not match the reading because of switched cable ends.

7.2: Connect the required length Sensor Harness to each Sensor installed with

the brake chambers. Note the harness orientation as that the Sensor and CCM use different connectors.

7.3: Route each Harness from the Sensor to the CCM. See Figures 8, 9.

• It is recommended that the e-Stroke harnesses are routed along with the vehicles existing wire harness as much as possible.

• Route harnesses along air lines from the actuator to the vehicle frame. The vehicle OEM designed and routed these air lines to account for suspension movement and steering articulation.

• Secure connectors together by routing a UV resistant (Black) cable tie through the connector clip. This will ensure the connectors are completely locked together. See Figure 8.

• Secure the connectors to an airline, cable harness bundles, or frame components using UV resistant (Black) cable ties around connector body. See Figure 9.

• Connectors must not be stressed or bent when secured.

• Connectors must be located in a serviceable location.

• Secure a minimum of 8” of slack harness near the connectors for future service.

7.4: Secure the Sensor Harnesses every 12-18” using UV resistant (Black) cable

ties. 7.5: Connect Sensor Harnesses to appropriate CCM connector for each wheel

end.
